you can "fake" it by inserting a column and putting the same number by the
ones you want to group, then do a subtotal on that column.

I have text in a spreedsheet we are using to organize a project. I want to
use the functionality of being able to roll up and unroll rows as we've all

the + and - buttons in key places so I can roll and unroll certain rows. Can
this be done?
